Jane Fonda says sex has had a ''big impact'' on her life.

The 79-year-old actress thinks she is one of many females in the world whose life has been ''profoundly affected'' by sexuality and not in a ''good way'', and she believes sexual abuse, ''betrayal'' and ''insecurity'' have become ''quite universal''.

Speaking to The Daily Telegraph's Stellar magazine the 'Monster-in-Law' star said: ''I don't think I'm the only woman whose life has been profoundly affected by issues of sexuality. Whether it's abuse, or wanting to please, or betrayal, or insecurity ... it's quite universal. Sex has had a big impact on my life - and not always in a good way.''

And Fonda believes people's perception of women has started to change over years, as she remembers a time when females weren't ''supposed to exercise''.

Fonda - who pioneered home exercise videos in the 80s - said: ''When I was starting out, women weren't supposed to exercise or have muscles.''

However, the 'Grace and Frankie' star - who retired from the entertainment business in the 1990s, only to make her comeback in 2005 - feels she has a new lease of life because she is working out.

She said: ''Now a lot of us, myself included, are staying active and healthier longer. I feel warmer and lighter. I had no idea that this was the case with advanced age. I feel, in a way, like I'm just starting out.''

Jane is not only working on her fitness but she is also working on bettering her relationships with her children Troy, 44, Vanessa, 49, and 50-year-old Mary - who she has from three different relationships - because she doesn't think she was always a ''good mother'' to her three kids.

Asked about her bond with her brood, she said: ''Pretty good, but a work in progress. I don't think the work between parents and children ever ends. Maybe some people are fine enough human beings that they do it right from the get-go. But most don't, and I certainly did not. I'm constantly having to learn and listen and ask for forgiveness and just try to get better at it, you know? The reality that I wasn't necessarily a good mother helped me play those things, actually.''
